Dinamic Y - Axis Title

aaraya

hello,
I have, a char in the header of a table group,
I need the axis Y text is changed dynamically,
I tested the following.

the column i need display in axis y is "unidad"

---

table group on create

var max = this.getRowData().getColumnValue("unidad");
reportContext.setPersistentGlobalVariable("unidad", max);

---

on char

---

function beforeGeneration( chart, icsc )
{
var ci = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("unidad");

xAxis = chart.getBaseAxes()[0];
yAxis = chart.getOrthogonalAxes( xAxis, true)[0];
yAxis.getTitle().getCaption().setValue(ci);

}


in the internal viewer works perfect,
but in tomcat viewer just repeats the same value for all group

using 3.7.2 version of birt.

tranks for your help.

I had a look at this problem but I was not able to find a solution.

I was able to reproduce the problem in BIRT 3.7.2. Your code actually works and modify the yaxis title dynamically, but it seems that every time you try to change the yaxis value all the charts are affected (on every group header).

I attach my report as example. If anyone have any idea on how to solve this problem it would be really interesting.


I also find strange that you are able to get it working in the designer. I don't.
